I am not sure if this is what you mean but this is what I do to see
what DB calls are being made. I add a print statement just before the
actual SQL call (which I actually print to the filehandle 'LOG' which
points to a log file). For example:
$db_update=$DB->prepare("UPDATE file_info SET file_size=?, file_perm=?,
file_acc_time=?, file_mod_time=?, file_user_uid=?, file_user_name=?,
file_group_uid=?, file_group_name=? WHERE file_parent_dir=? AND
file_name=? AND file_type=?") || die...
...
if ( $log_level >= 4 ) { print LOG " |- ".__LINE__." DBI: UPDATE
file_info_".$dev_id." SET file_size=$size, file_perm=$mode,
file_acc_time=$atime, file_mod_time=$mtime, file_user_uid=$uid,
file_user_name=$user, file_group_uid=$gid, file_group_name=$group WHERE
file_parent_dir='/' AND file_name='.' AND file_type='d';\n"; }
$db_update->execute($size, $mode, $atime, $mtime, $uid, $user, $gid,
$group, "/", ".", "d") || die...
Noting of course that the quoting might be slightly off because a
prepared statement automatically quotes values as needed. If you wanted
to be really carefully you could quote the values for your log like so:
if ( $log_level >= 4 )
{
$db_user=$DB->quote($user);
$db_group=$DB->quote($group);
print LOG " |- ".__LINE__." DBI: UPDATE file_info SET file_size=$size,
file_perm=$mode, file_acc_time=$atime, file_mod_time=$mtime,
file_user_uid=$uid, file_user_name=$db_user, file_group_uid=$gid,
file_group_name=$db_group WHERE file_parent_dir='/' AND file_name='.'
AND file_type='d';\n";
}
I hope this was along the lines of your question.
